JI'I-IN Gr. MACCUNE, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR OF ONE-HALF '170 FRANK I'I. PETERSON, 0F MINNEAPOLIS, MINNESOTA EMBROIDERY-HOOP.

Specication of Letters Patent.

Patented Mar. 3, 1914.

To all whom t may concern Be it known that I, JOHN Gr. MACCUNE, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Improvements in 'Embroidery Hoops, of which the following is a specification.

In embroidery hoops as usually constructed the spring device provided in connection with one of the rings for causing it to grip the cloth to be embroidered frequently becomes weakened so that the rings, instead of fitting snugly together, will be loose and will not grip the cloth securely.

The object of my invention is to entirely obviate this objection in an embroidery hoop and provide a construction which at all times will cause the cloth to be securely gripped and irmly held.

A further object is to provide an embroidery hoop of simple construction and one which can be easily operated. In the accompanying drawings Yforming part oi' this speciiication, Figure 1 is a sectional view of an embroidery hoop embodyr ing my invention, on the line arf-:r of Fig. 2, Fig. 2 is an edge View of the same, showing the rings partially separated from one another preparatory to the insertion of the cloth between them. Fig. 3 is a sectional view, showing a reversal of the construction illustrated in Figs. 1 and 2, on the line y-g/ of Fig. 4, Fig. 4 is a sectional view through the hoop shown in Fig. 3, showing the rings partially separated, Fig. 5 is a plan view showing a construction in which the spring is omitted, the cloth being gripped by the tension of the rings upon one another,` Fig. 6 is a sectional view of the same.

In the drawing, 2 represents the outer ring, cut transversely at 3 and having an annular groove or depression 4 formed therein to receive a spring device 5. A second ring 6 is provided, adapted to iit within the ring 2 and having an annular groove 7 to receive the rib formed on the inner surface of the ring 2 by the pressing of the groove 4 therein. These rings may be made of any suitable material, preferably ber, which on account of its toughness and durability and comparative light weight forms a very suitable material for a device of this kind. The ring 6 is made of sufficient diameter to separate or spread the ends of the ring 2 and put the spring 5 under tension so that when the cloth to be embroidered is placed over the ring G and the ring and cloth thrust into the ring 2, the cloth will be securely clamped between the two rings and positively held against slipping during the elnbroidering operation. The spring 5 extends almost en tirely around the ring 2 and supports and braces it at all points, and the strain on the spring is so evenly distributed throughout its length that it will not become weakened through use and will exert a steady, uniform pressure on the outer ring and cause it to grip the cloth at all points of Contact therewith.

In Figs. 3 and 4 the arrangement of the parts is reversed. The outer ring S is made continuous and the inner ring 9 is cut transversely at 10 and provided on its inner sur face with an annular groove or recess 11 to receive a spring 12, corresponding to the one described, and adapted to exert an outward pressure to force the rib 13 into the annular groove 14 provided in the ring 8. The cloth to be embroidered will be inserted between the rings in the manner described with rei erence to Figs. 1 and 2 and the pressure of the ring will be uniform at all points on the cloth.

In Figs. 5 and 6 I have illustrated another modification, which consists in providing an outer ring 15 having an annular rib 16 formed on its inner surface and cut trans versely at 17. This transverse cut is irregularly formed, so that there will be no gap between the ends of the ring when the fabric is inserted between it and the inner ring. rl`he inner or second ring 18 is preferably provided with an internal annular groove 19 to receive the rib 16 but the ring, instead of being cut transversely, is continuous. These rings may be formed of fiber or of wood havinga suflicient degree of spring t0 grip the fabric when the cloth to be embroidered is inserted between the rings. I prefer, however, to use the construction in which the metallic circular spring is eniployed to clamp the split ring on the work, as the long bearing of this circular spring on the ring will produce a uniform pressure on the cloth and be far more durable than a coiled spring or similar device located at the ends of the ring.

The device may be made in various sizes and various means may be employed for mounting the spring on the ring and still be within the scope of my invention.

I claim as my invention 1. An embroidery hoop comprising an inner continuous ring, an outer ring split or divided transversely and adapted to be expanded sufficiently to encircle said inner ring, said rings having annular grooves or depressions therein and a spring consisting of a metal hoop divided transversely at one point and adapted to encircle said rings and bear uniformly thereon and cause said rings to exert a uniform pressure on the cloth inserted between them,

2. An embroidery hoop comprising an inner and an outer ring, one of said rings being split or divided transversely and adapted to grip the adjacent surface of the other ring, said rings having grooves or depressions therein and a spring hoop divided transversely at one point and fitting Within one of said grooves and bearing uniformly on said rings and causing them to eXert a uniform pressure on the cloth inserted betWeen them.

In Witness whereof, I have hereunto set my hand this l2 day of September, 1912.
